I picked up 12 Soundstream Van Gogh Amps 4-VGA600.2 8-VGA400.2 and Two Soundstream DV10 Subs. The Van Gogh Amps (VGA600.2) are rated
4Ohm Stereo/2Ohm Stereo/4Ohm Mono
VGA600.2 / 150w X 2ch / 300w X 2ch / 600w X 1ch

Can I run Two 4Ohm Subs in Stereo???? I do not know how to get two 4Ohm subs to see the 4Ohm Bridged Mono?

The subs conected would be Alpine Type R 10" Dual Voice Coil 2Ohm+2Ohm but could get the Dual 4Ohm+4Ohm (If I went with the Dual 4+4 could I get a 4Ohm Load from both so the amp could power them in Mono?

I just want to power the two subs with one amp but not sure how to run since it will only show Mono at 4Ohms.

Thanks For the help???????

    I dont think I know what youre asking.

    You can run a pair of 4 ohm DVC subs as 4 ohms mono. Wire them in series with each other and then in parallel with the amp. Wiring them in series will make them 8 ohms each - then in parallel with the amp for the 4 ohms mono.

    What about running a set of subs 2 ohm stereo versus mono?
    I figured out all the wiring of the subs just not sure about the stereo versus mono on subs.

    The wiring of the voice coil would have nothing to do with the amp seeing a mono or stereo. Right?

    Bridging a pair of channels is what tells the amp that it is a mono load versus running a sub weather it be 2 ohm or 4 ohm wired to say channel one and the other to channel two making it see stereo.

    My issue is with these Soundstream Van Gogh VGA-600.2 amps that I got to go in the wifes car. They only allow for 2-4 ohm stereo to two channels or 4 ohm mono bridged to one channel. I had already purchased a pair of dual 2ohm Alpine type-s's and they do not seem like they can be wired to work and get full power from the amp. Would I be better to run them 2Ohm Stereo or 4Ohm Mono and what is the difference?

    4Ohm Stereo/2Ohm Stereo/4Ohm Mono
    VGA600.2 / 150w X 2ch / 300w X 2ch / 600w X 1ch

    I Hope I broke this down better I just want to fully understand because I thought I knew how it worked untill I talked to a Soundstream tech and he said by wiring the two subs(Dual 2ohmVC) up it would make them show 2ohm MONO and I had thought MONO had to do with how they are connected to the amp not the wiring of the Voice Coil.
